Applying the Model-Driven Architecture Approach to Dynamic Structure Applications

International audienceModel-Driven Architecture (MDA) is a system engineering approach which consists in separating the model description from the execution platform. It allows building a model without detailed knowledge of the target platform, as well as retargeting the execution platform without changing the model itself. We present a meta-model called Partial Reconfigurable DEVS (PRDEVS) that is able to represent dynamic structure changes of a model. We base our approach on the DEVS formalism, which is modular and hierarchical. Our description paradigm differs from the previous DEVS-based dynamic meta-models in that it explicitly deals with adding and removing components. This approach is closer to the general reconfigurable embedded system design methodology. Both a software and a FPGA-based hardware platform are considered as dynamic execution platforms
